GENUS AND SPECIES

Phalaenopsis Blume

VARIETY DENOMINATION

‘PHALDANXOK’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar ofPhalaenopsis plant, botanically known as Phalaenopsis of the Orchidaceaefamily, and hereinafter referred to by the cultivar name ‘PHALDANXOK’.

Phalaenopsis comprises a genus of about 60 species of herbaceousperennials many of which, or the hybrids thereof, are suitable forcultivar in the home or greenhouse. Phalaenopsis is predominantlyepiphytic or rock dwelling, and is native to tropical Asia, the MalayArchipelago, and Oceania. The species typically has 2-ranked, fleshy,oblong or elliptic leaves affixed to a short central stem (monopodialgrowth), which vary in size from 12 to 20 cm to over 60 cm. The leavesmay be entirely green or mottled with silver grey.

Phalaenopsis orchids, often referred to as ‘Moth Orchids’ in thehorticultural trade, are frequently used to furnish cut flowers for theflorist trade or sold as flowering potted-plants for home orinteriorscape.

Phalaenopsis produces upright or pendent lateral racemes or panicle,often with many showy flowers which open in succession beginning withthe lowermost. The flowers possess three sepals and three petals; thelateral ones being alike. The lowermost petals, called the labellum, isthree-lobed and is often more brightly-colored than the other flowersegments. Flower colors include various shades of pink, white, yellow,and red-brown.

Phalaenopsis orchids are typically propagated from seeds. Asexualpropagation of Phalaenopsis is often done from off-shoots which arisefrom the lower bracts of the inflorescence. The resulting plants aredetached from the mother plants and may be planted in a suitablesubstrate.

The new Phalaenopsis ‘PHALDANXOK’ is particularly characterized by itsattractive and unique lilac flowers, economical propagation by tissueculture, rapid growth, and a plant dimension suitable for packaging andshipping to the market.

‘PHALDANXOK’ is a product of a planned breeding program conducted inBleiswijk, The Netherlands.

The new Phalaenopsis ‘PHALDANXOK’ originated from a cross made inFebruary 2002 in Bleiswijk, The Netherlands. The female parent is a pinkPhalaenopsis pot plant named ‘07904-0009’ (unpatented), while the maleparent is a white Phalaenopsis pot plant named ‘05174-0001’(unpatented). A single plant was selected in March 2007 and has beenasexually reproduced repeatedly by tissue culture in Bleiswijk, TheNetherlands over a 4-year period. The new variety has been found toretain its distinctive characteristics through successive asexualpropagations.

Asexual reproduction of ‘PHALDANXOK’ by tissue culture was firstperformed in July 2010 in Bleiswijk, The Netherlands and hasdemonstrated that the new cultivar is firmly fixed and retained throughsuccessive generations of asexual reproduction.

Plant Breeder's Rights for this variety have been applied for in Europeon Sep. 20, 2013. ‘PHALDANXOK’ has not been made publicly available orsold anywhere in the world more than one year prior to the filing dateof this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new cultivar when grown under normalhorticultural practices in Bleiswijk, The Netherlands.

1) Lilac flowers;

2) 2 peduncles;

3) Inflorescence is long and moderate;

4) The shape of the leaf is lanceolate; and

5) Plants are propagated by tissue culture.

DESCRIPTION OF THE PHOTOGRAPHS

This new Phalaenopsis plant is illustrated by the accompanyingphotographs which show the overall plant habit including blooms, budsand foliage of the plant; the colors shown are as true as can bereasonably obtained by conventional photographic procedures. Thephotographs are of a 50-week old plant grown in a greenhouse inBleiswijk, The Netherlands in March 2014.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘PHALDANXOK’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 50-week oldplants which were planted from tissue culture in 12 centimeter pots andgrown in a greenhouse between 27° C. to 29° C. for 30 weeks, continuedby a cooling period of 8 weeks between 18° C. to 20° C. and 12 weeks ina greenhouse of 21° C. Observations were made in March 2014. Colorreadings were taken under 4-6000 lux natural light in the greenhouse.Color references are primarily to The R.H.S. Colour Chart of The RoyalHorticultural Society of London (R.H.S.) (2001).

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘PHALDANXOK’ differs from female parent ‘07904-0009’ (unpatented) inthat ‘PHALDANXOK’ has a copper colored lip, whereas ‘07904-0009’ has anorange colored lip. Additionally, the apical lobe of the lip of‘PHALDANXOK’ is shorter than that of ‘07904-0009’ and the callus of thelip of ‘PHALDANXOK’ is more yellow (RHS 14A), whereas ‘07904-0009’ ismore orange (RHS 23A).

Additionally, thecallus of ‘PHALDANXOK’ is yellow dotted (RHS 14A and 178A), whereas thecallus of ‘PHALBOCIQ’ is yellow (RHS 5B) and the type of curvature ofthe lateral lobe of ‘PHALDANXOK’ is type I, whereas the type ofcurvature of the lateral lobe of ‘PHALBOCIQ’ is type III.

I claim:
 1. A new and distinct variety of Phalaenopsis plant named‘PHALDANXOK’ as shown and described herein.
